"I'm unable to give all of my guests a plus-one. I feel bad, but we are on a budget! How do I approach this?" —Megan S. of Arcata, Calif., via Facebook

Dear Megan,

This is nothing to feel bad about. "Hello, recession? It's me, Megan." At least 99 percent of the population is on a budget, so your friends should understand. A common approach is to include only the guests of friends in serious relationships. Address the invitation to them both by name, never as "Ms. Emily Becker and Guest." When you speak to your single friends or those in less serious relationships, tell them the situation—without embarrassment or defensiveness. And if there are enough single guests at your wedding, maybe romance will strike—at least for the night!
